Zendesk Support and Data Protection – What Belongs in the Privacy Policy
Concise guide to Zendesk: customer support, chat, data processed, purposes, legal bases (GDPR) and what website operators must include in their privacy policy.
Zendesk Support and Data Protection – What Website Operators Need to Know
If a website operator uses Zendesk for customer support and live chat, they process contact data (name, email, phone, support inquiry), chat messages and ticketing data for the purpose of customer communication and support handling on the basis of legitimate interests and, where applicable, contract performance. Zendesk International Ltd, Dublin, Ireland, acts as a processor and not as a controller – the website operator bears the main responsibility for the data processing.
This guide is aimed at website operators who use Zendesk Support, Zendesk Chat or Zendesk Ticketing and therefore need a GDPR-compliant privacy policy.
A. Purpose and Function of Zendesk
Zendesk is a cloud-based customer support platform with several functional modules:
- Zendesk Support (Ticketing): Website visitors submit support requests via a form or email; the website operator manages these tickets in a Zendesk dashboard
- Zendesk Chat (Live Chat): A live chat widget on the website enables direct communication between visitor and support agent in real time
- Zendesk Messaging: Messaging via WhatsApp, SMS, Messenger and other channels
- Knowledge Base: Public FAQ and self-service articles
The typical integration takes place via:
- Chat widget: A JavaScript snippet on the website displays a small chat window
- Support form: A contact form sends inquiries to Zendesk
- Email integration: Support inquiries can also be submitted by email
When in use, contact and communication data is transmitted to the Zendesk servers, where it is stored, searched and analyzed in a ticketing system.
B. Mandatory Disclosures in the Privacy Policy regarding Zendesk
The GDPR requires for every processor: purposes (Art. 13(1)(c)), legal bases (Art. 13(1)(a)), categories of recipients (Art. 13(1)(e)), third-country transfers (Art. 13(1)(f), if relevant) and storage duration (Art. 13(2)(a)).
Perspective on Zendesk integration: Many website operators only write about Zendesk »Zendesk processes support requests« – this is too short and not meaningful. Instead, the following should become clear:
- Who is Zendesk (processor in Dublin)?
- What data flows (name, email, chat content)?
- What purpose (support handling, ticketing)?
- What legal basis (legitimate interests, possibly contract)?
- Where is data processed (server locations)?
Better: A topic-oriented section »Customer communication and support« with a list of all support tools (Zendesk, mail, phone).
Privacy policy in minutes — easy to maintain, no subscription.
Instead of an unreadable text block per tool: a topic-oriented, hybrid approach with a clear list of recipients — maintainable, transparent, GDPR-compliant.
- No subscription, no hidden costs
- Easy to maintain thanks to a topic-based structure instead of tool-by-tool blocks

G. Legal Bases for Zendesk
Step 1: Categorization of Zendesk Zendesk is a processor (Art. 28 GDPR). The website operator is the controller and bears responsibility for ensuring that:
- A legal basis for the processing exists
- Data subject rights are guaranteed
- A DPA with Zendesk exists
Step 2: Applicable legal bases
-
Legitimate interests (Art. 6(1)(f) GDPR) – primary:
- The website operator has a legitimate interest in offering customer support
- Customer communication improves the business relationship
- Ticketing enables tracking and documentation of inquiries
- The interests of the website operator outweigh the interests of the data subjects, since the processing is necessary and foreseeable
- Balancing: The data subject expects that a support contact will be documented
-
Contract performance (Art. 6(1)(b) GDPR) – secondary:
- If the data subject submits a support ticket, storage is necessary for the fulfilment of the support promise
- Storage and processing are contractually required
-
Consent (Art. 6(1)(a) GDPR) – optional:
- Not required, since legitimate interests are sufficient
- Optional: If the website operator uses chat data for marketing (e.g. remarketing lists), consent is required
Special feature – § 25 TDDDG: If the chat widget also sets cookies (e.g. for session tracking or visitor recognition), opt-in consent is required (§ 25(1) TDDDG). Pure support functionality without tracking cookies does not require additional consent.
H. Special Features and Notes regarding Zendesk
1. Processor with own controller status Zendesk is a processor for the website operator, but also a controller for its own processing (e.g. product improvement, security research). This means:
- You are the controller for the support data you collect
- Zendesk is the processor for the technical storage
- Zendesk is also the controller for internal analytics and security analyses
2. DPA is mandatorily required You must have a Data Processing Agreement (DPA) with Zendesk. This is available at https://www.zendesk.com/company/data-processing-agreement/ and regulates:
- Data processing under Art. 28 GDPR
- Subprocessor approval
- Security standards (BSI C5, ISO 27001)
- Support for data subject rights
Without a DPA, you violate Art. 28 GDPR.
3. Subprocessors and third-country transfers Zendesk uses subprocessors for hosting (AWS), analytics and security. Many of these subprocessors are based in the USA. Applicable transfer mechanisms:
- Data Privacy Framework (DPF): Zendesk uses DPF for US subprocessors (check https://www.dataprivacyframework.gov/s/participant-search)
- Standard Contractual Clauses (SCC): For other US transfers
- Binding Corporate Rules (BCR): Zendesk operates its own BCR for intra-group transfers
You should disclose in your privacy policy: »Support data is partly transferred to AWS in the USA. Zendesk uses Data Privacy Framework and Standard Contractual Clauses.«
4. Data subject rights and Zendesk Data subjects can request access to, rectification of or erasure of their support ticket (Art. 15–17 GDPR). You must:
- Have a procedure for receiving deletion requests (e.g. by email)
- Forward these requests to Zendesk
- Zendesk supports you with implementation (regulated by DPA)
5. Storage duration and compliance You can retain support data for any length of time. Zendesk itself deletes data within 30 days of your deletion. Recommendation: Document your retention policies (e.g. »Support tickets 2 years«).
I. FAQ on Zendesk
J. Conclusion and Recommendation regarding Zendesk
Zendesk is a proven support tool, but it is complex from a data protection perspective: processor structure, third-country transfers to the USA, subprocessors, and various legal bases.
Tool-specific text templates (»Zendesk processes support requests«) are too short and do not meet the GDPR requirements.
Recommendation: Use a topic-oriented structure:
- Section »Customer communication and support« with description of all support channels (chat, email, phone)
- Section »Data subject rights« with info on access and deletion requests
- Section »Third-country transfers« with reference to DPF/SCC
- Appendix with subprocessor list (available from Zendesk)
Make sure that:
- The DPA with Zendesk is signed
- You have the current subprocessor list
- An internal process for data subject rights requests exists
